Damage Model of Concrete Durability under Coupled Action of Stress and Freeze-Thaw Cycles
Based on damage mechanics and thermo, the mechanical degradation of concrete material under the coupled action of stress and freeze-thaw cycles was analyzed in this paper. The tensile stress in concrete during freeze-thaw cycles was obtained considering freezing-induced pore pressure variation with the change of temperature. A revised fatigue fracture model is proposed for the reliability analysis of concrete durability, which can evaluate damage status and the remaining service life of concrete structure after freeze-thaw cycles with different loading levels. The present model can serve as references for design and safety assessment for concrete structures in cold regions.
